Filamentous tangles with nemaline rods in MYH2 myopathy: a novel phenotype

Acta Neuropathologica Communications, 2021
The MYH2 gene encodes the skeletal muscle myosin heavy chain IIA (MyHC-IIA) isoform, which is expressed in the fast twitch type 2A fibers. Autosomal dominant or recessive pathogenic variants in MYH2 lead to congenital myopathy clinically featured by ...

Case report: identification of one frameshift variant and two in cis non-canonical splice variants of NEB gene in prenatal arthrogryposis

Frontiers in Genetics, 2023
NEB mutation is associated with congenital nemaline myopathies. Here, we report a family with recurrent prenatal arthrogryposis. Trio whole exome sequencing (WES) disclosed three novel NEB (NM_001271208.2) variants including one paternal frameshift c ...

Mutation update and genotype-phenotype correlations of novel and previously described mutations in TPM2 and TPM3 causing congenital myopathies [PDF]

, 2014
Mutations affecting skeletal muscle isoforms of the tropomyosin genes may cause nemaline myopathy, cap myopathy, core-rod myopathy, congenital fiber-type disproportion, distal arthrogryposes, and Escobar syndrome.

Case Report: Monoclonal Gammopathies of Clinical Significance-Associated Myopathy: A Case-Based Review

Frontiers in Oncology, 2022
Monoclonal gammopathies of clinical significance (MGCS)-associated myopathy is a group of muscular MGCS-based rare manifestations. It mainly includes amyloid light chain (AL) amyloidosis and sporadic late-onset nemaline myopathy with monoclonal ...

Mutations in repeating structural motifs of tropomyosin cause gain of function in skeletal muscle myopathy patients [PDF]

, 2013
The congenital myopathies include a wide spectrum of clinically, histologically and genetically variable neuromuscular disorders many of which are caused by mutations in genes for sarcomeric proteins.

Testing of therapies in a novel nebulin nemaline myopathy model demonstrate a lack of efficacy

Acta Neuropathologica Communications, 2018
Nemaline myopathies are heterogeneous congenital muscle disorders causing skeletal muscle weakness and, in some cases, death soon after birth. Mutations in nebulin, encoding a large sarcomeric protein required for thin filament function, are responsible ...

Clinical and genetic features of infancy-onset congenital myopathies from a Chinese paediatric centre

BMC Pediatrics, 2022
Background Congenital myopathies are a group of rare neuromuscular diseases characterized by specific histopathological features. The relationship between the pathologies and the genetic causes is complex, and the prevalence of myopathy-causing genes ...

Molecular signatures of inherited and acquired sporadic late onset nemaline myopathies

Acta Neuropathologica Communications, 2023
Acquired sporadic late onset nemaline myopathy (SLONM) and inherited nemaline myopathy (iNM) both feature accumulation of nemaline rods in muscle fibers. Unlike iNM, SLONM is amenable to therapy.
